REGISTRES «INPUT» (Voir Table «Input registers»)
Les registres d'entrée sont en lecture seule. Toutes les données peuvent être lues
par la commande “Read Inputs Registers”. Tableau 1 Registres Modbus indique le
type de données retourné et la façon dont il doit être interprété.
REGISTRES «HOLDING»(Voir Table «Holding registers» )
Ces registres sont lecture / écriture et ils peuvent être gérés avec les commandes
'Read Holding Registers', 'Write single register’ et 'Write Multiple Registers'. Les
registres qui ne sont pas utilisés, sont en lecture seule et, par conséquent, écrire
dans ces registres ne rend pas d'échec Modbus, ni apporte des changements.
